Simple Decision Tree Editor

I need a decision tree editor made. The editor must be able to save the decision tree to and from an XML file. I will prefer if it is made in C++, Java or C#. It should be similar to this [login to view URL] . Also, it should be saved in this xml format <node><yes_child><child_node><\child_node><\yes_child><no_child><child_node><\child_node><\no_child><\node>
